HandBrake

Posted: **Tue Jun 14, 2016 11:24 pm**

Hi,
It's been a short time since I discovered HandBrake. I wish I've known for longer. Decent program!

I'm sure there's been many similar questions to this one, but I couldn't find this specific thing: using the CLI to convert each group of videos to their own output folder in Windows 10, HandBrake version 0.10.5.0 64b.

Example:

I have some dirs with videos taken from an iPhone camera:

* E:\Dropbox\Videos\From iPhone\Vacation 2013\many-from-2013.mov
* E:\Dropbox\Videos\From iPhone\Vacation 2014\many-from-2014.mov
* E:\Dropbox\Videos\From iPhone\Vacation 2015\many-from-2015.mov

They're all in 1920x1080 .mov format and take a lot of storage. I'd like to reduce them to 1280x720 and possibly reduce the framerate from 29 to 23.976, or whatever solution you can suggest me to reduce file size.

So I tried:

Code: Select all

HandBrakeCLI -v -i "E:\Dropbox\Videos\From iPhone\Vacation 2013\" -o "E:\Dropbox\Videos\From iPhone converted" -w 1280 -O -e x264 -q 22

But the above only applies to a single folder to be converted, so I have to wait and then modify the command to get to the next. What I want is to do be able to convert all of the above videos under any subdir of E:\Dropbox\Videos\From iPhone\, at once, and have this output:

* E:\Dropbox\Videos\From iPhone converted\Vacation 2013\many-from-2013.mp4
* E:\Dropbox\Videos\From iPhone converted\Vacation 2014\many-from-2014.mp4
* E:\Dropbox\Videos\From iPhone converted\Vacation 2015\many-from-2015.mp4

...so that none would overwrite the originals. How can I do it?

Obs. I didn't provide the encode log because the individual approaches I make are successful themselves, so it's not the point.

You can use batch files to do this. They're simple to construct in any text editor (including notepad), and you can even edit them to add more lines while their running, so long as you don't make any changes prior to the currently-running command... I do it all the time. If you insert something like this in front of each line, you can even keep track of where it is:

Code: Select all

title "many-from-2013" &

The CMD window title will show "many-from-2013" while the encode is running.

Pretty easy to write a batch script to iterate through each file and set the output appropriately.

Encode logs can still be useful, regardless of your opinion. You'll note the header makes no exception for "unless you don't think so".

Perhaps you could post a working example?

Searching for "script" gives too many hits here, but scrolling down through the CLI forum, there are a few that are "off the top page".

There are more with "script" in the subject after you get past page 6.

Thanks for your responses!

I've seen those, actually two are the same, and none address the actual problem. They're about 'creating a script', but everything I've seen here is based on Unix-like OS'es and some bash scripts, which don't work on Windows. Also, one (two) of them require Ruby installed, and possibly would require Ruby knowledge if I were to make modifications

Apparently not, since, for each group of encodes, I'd have to modify the batch script. And sorry about not posting the log, I thought it wasn't exactly mandatory. I have the following, but nonetheless, it's pointless. See why:

To make things simpler, I've created a minimalistic test tree:

E:\test\source\vacation2013\2013 1.mov
E:\test\source\vacation2013\2013 2.mov
E:\test\source\vacation2013\2013 3.mov

E:\test\source\vacation2014\2014 1.mov
E:\test\source\vacation2014\2014 2.mov
E:\test\source\vacation2014\2014 3.mov

E:\test\source\vacation2015\2015 1.mov
E:\test\source\vacation2015\2015 2.mov
E:\test\source\vacation2015\2015 3.mov

The destination was supposed to be like...

E:\test\destination\vacation201[3-5] reduced\201[3-5] [1-3].mp4

Which is the same as...

E:\test\destination\vacation2013-reduced\2013 1.mp4
E:\test\destination\vacation2013-reduced\2013 2.mp4
E:\test\destination\vacation2013-reduced\2013 3.mp4

E:\test\destination\vacation2014-reduced\2014 1.mp4
E:\test\destination\vacation2014-reduced\2014 2.mp4
E:\test\destination\vacation2014-reduced\2014 3.mp4

E:\test\destination\vacation2015-reduced\2015 1.mp4
E:\test\destination\vacation2015-reduced\2015 2.mp4
E:\test\destination\vacation2015-reduced\2015 3.mp4

But if I simply run this...

Code: Select all

HandBrakeCLI -v -i "E:\test\source" -o "E:\test\destination\"

I get this:

Code: Select all

Output format can't be guessed from file name (E:\test\destination), using default.

Seems obvious, right? After all, I didn't use any options. But I don't see anything like a -r or -R option to "recurse" subdirectories so the program could find the .mov files inside. And, if I delve to the actual dir containing the .mov files, then the purpose of the opening question would be forfeit.

So, what could I do besides creating a specific script for each situation?

So, anyone? I don't see a way to circumvent the need for a -R option to recurse subdirectories...

Posted: **Fri Jun 24, 2016 6:44 am**

There is no -r option, if you want to search through directories and sub directories you will have to script it.

Thanks Rollin_eng.
That's sad to hear, because although one can make a script, it is not very nice to have to create a script for every batch job...

This could serve as a feature suggestion for the developers, though.

Posted: **Sat Jun 25, 2016 9:35 am**

There is a feature request forum, you could search it to see if this has been requested before.

You can script the CLI to do pretty much anything, including going through multiple folders/sub-folders.

If this is a one off project doing individual batches/folders may be the easiest way to go, if this is something you envision doing often then learning how to write a script to search through multiple folders might be the better option.

Thanks rollin_eng!
I guess I'll try to script my way out.
